Reaction Kinetics of Ozonation of Trichloroethylene and Benzene in Gas and Liquid Phases

摘要

The kinetics of ozonation reactions of trichloroethylene (TCE) and benzene in gas and liquid phases at 101.3 kPa and 298 K was investigated in this paper. The ozonation of TCE is first order with respect to the ozone con- centration and one and half order to TCE in the gas phase with the average rate constant 57.30 (mol. L~-1)~-1.5.s~-1, and the TCE ozonation in aqueous medium is first order with respect to both ozone and trichloroethylene with the average rate constant 6.30 (mol.L~-1)~-1.s~-1.
